IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 217,368, dated July 8,1879 application filed April 29, 1879.

To all whom it may concern:

Be it known that I, AMANDES HAGKMAN, of Blakesburg, in the county ofWapello and .State of Iowa, have invented a new and useful Improvementin Plows, of which the following is a specification.

Figure 1 is a side view of a plow to which my improvement'has beenapplied. Fig. 2 is a top view of the same. Fig. 3 is a cross-section ofthe beam and beam socket, taken through the line a: as, Fig. 4. Fig. 4is a detail section of the beam-socket, taken through the line 3 y, Fig.3. Fig. 5 is a detail side and edge view of one of the slotted wedges.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish plows which shallbe soconstructed that they may be readily adjusted to cut a deeper, ashallower, a wider, or a narrower furrow, as may be desired, and whichshall be simple in construction and convenient and reliable in use,being easily adjusted, and holding the plow firmly and securely inplace.

The invention consists in the combination of the socket provided withslots, the swiveled screws, and the slotted wedges with the standard andthe beam, as hereinafter fully described.

A represents the beam, B thehandles, U the mold-boards, D the land-side,and E the standard, of a plow. Upon the upper end of the standard E isformed, or to it is attached, a

socket, F, through which the beam A passes, and the cavity of which ismade larger than the beam A, so that the said beam may have a verticaland a lateral movement within the said socket.

The socket F projects in front of the forward edge of the standard E,and. in the upper and lower side of the said projecting part are formedshort cross-slots f, in which are swiveled the ends of a screw, G, whichpasses vertically through the beam A.

In case the beam Ais wood a nut, 9, should be let into it for the screwG to pass through. In case the beam A is iron a screw-hole is formedthrough it to receive the screw G, so that the beamA can be raised andlowered to adjust the plow to cut a deeper or shallower furrow byturning the said screw G.

In the sides of the socketF are formed short vertical slots f, in whichare swiveled :the ends of a screw, H, which passesthrough the beam A.

In case the beam A be wood a nut, h, should be let into it to receivethe screw H. In case the beam A be iron a screw-hole may be formedthrough it to receive the said screw H, so that the beam A can be movedlaterally toa'djust the plow to cut a wider or a narrower furrow turningthe said screw H.

I are wedges, which are slotted longitudinally from their forward endsto receivethe screws G H, so that they can be driven into the socket Fabove and at the sides of the beam A when adjusted, to protect the saidscrews G H from lateral strain.

. To the under side of the beam A, at the rear of the socket F, isattached an arm of an angle-iron, J, the other arm of which projectsdownward for the lower part of the socket F to rest against, tostrengthen the standard E against the draft-strain and relieve the boltsHaving thus described my invention, I claim as new and desire to secureby Letters Patent with the slots f f the swiveled screws G H, and theslotted wedges I with the standard E and the beam A, substantially asand for the purpose set forth.
